I would like to add how to setup support as well as you mentioned you wish to use the support ticketing system as well.
To do this you will need to do the following
Settings>Plugins>Available>Support Manager
Then as the Plugin will tells you will need to configure yourself and/or staffs as per setup
To do so go to "Support" which will be next your "Tools" and then you will need to add at least one department and staff.
To add a Department do..
Support>Department>Add Department
To add a Staff do..
Support>Staff>Add Staff
Both will have configurations that you will need to fills out to create them. I hope this helps you out and once you get a hang of it then it should be pretty straight forwarded.
